The search continued Tuesday for a missing Fair Haven man who disappeared early Saturday morning while walking along Route 149 near the New York/Vermont state line.

Jonathan Schaff left a Granville, N.Y., bar about 4:30 a.m. where he had been in a fight earlier.

He and two other people were walking to a car parked east of the bar in a trucking company parking lot just across the state line. When the other two stopped for a moment, Schaff kept walking, and was never seen again.

The Vermont State Police conducted an air search Tuesday with an Army National Guard helicopter.

Lt. Michael Manley of the Vermont State Police said the search checked rivers, fields and roads in the area without any success.

The search perimeter also expanded 5 to 6 miles beyond the initial search area, which has focused on the area around the state line on Route 149 and logical paths of travel from that area.

Manley also asked that anyone living within about 5 miles of that area check their property, looking in any sheds, vehicles and other places a person might have sought shelter.

With temperatures dropping below zero overnight, searchers said weather is the top concern for Schaff.
